Abstract
Let A be a fixed 2×2 integral matrix with irrational characteristic roots. Let B be an arbitrary 2×2 integral matrix. It was previously shown that -det (AB-BA) = norm λ, where λ is in the field of the characteristic roots of A. It is now shown that the λ's corresponding to varying B's can be chosen to form a fractional ideal in this field.
